Add support for CBL-Mariner and Azure Linux

[hbeberman]

This PR adds support for mariner and azurelinux in the getOSVersion helper function.

Azure Linux (aka CBL-Mariner) is a Linux distribution maintained by Microsoft which is currently available in Azure Kubernetes Service and is also used in other parts of the cloud infrastructure and edge products.

For a few years we've been using a patched version of node-problem-detector which adds Mariner into this switch case. I'm looking to get "mariner" and the upcoming os-release name of "azurelinux" added into node-problem-detector directly so that we can drop the patch and be compatible with instances of the binary built outside of our distro.

Hi @hbeberman. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

The change looks ok to me. Today we do not have any OSS E2E test coverage for those os types. Do you want to add them? This is not a requirement for this PR. But I think it may be beneficial to you.

@hakman sorry for the delay! I was making sure everything was squared away to sign the CLA from my side, but I've now signed it.

@wangzhen127 great suggestion on the E2Es. I'm looking into the implementation details and will follow up with a separate contribution if it's something we can add for Mariner / Azure Linux.
